What is the maximal age a Indian rhinoceros reaches?
An adult Indian rhinoceros (Rhinoceros unicornis) usually gets as old as 49 years.
Indian rhinoceross are around 478 days in the womb of their mother. When born, they weight 61.35 kg (135.26 lbs) and measure 1.09 meter (3′ 7″). As a member of the Rhinocerotidae family (genus: Rhinoceros), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 3.74 meter (12′ 4″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The Indian rhinoceros (Rhinoceros unicornis), also called the greater one-horned rhinoceros and great Indian rhinoceros is a rhinoceros species native to the Indian subcontinent. It is listed as Vulnerable on the IUCN Red List, as populations are fragmented and restricted to less than 20,000 km2 (7,700 sq mi). Moreover, the extent and quality of the rhino’s most important habitat, the alluvial Terai-Duar savanna and grasslands and riverine forest, is considered to be in decline due to human and livestock encroachment. As of 2008, a total of 2,575 mature individuals were estimated to live in the wild.The Indian rhinoceros once ranged throughout the entire stretch of the Indo-Gangetic Plain, but excessive hunting and agricultural development reduced its range drastically to 11 sites in northern India and southern Nepal. In the early 1990s, between 1,870 and 1,895 rhinos were estimated to have been alive.
